Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) using a first radio access technology (RAT) may transmit a channel reservation preamble of a second RAT (e.g., a Wi-Fi preamble) that provides an indication to devices of the second RAT that the UE has obtained a shared channel for a channel occupancy time (COT). The UE may determine a start time of the channel reservation preamble relative to a start time of a first symbol of a transmission slot based at least in part on a time duration of the first symbol. The channel reservation preamble may reserve multiple slots or a single slot. A UE transmitting on two or more sub-channels may transmit a preamble on one of the sub-channels or on each of the sub-channels.

Abstract: Systems and methods for detecting a body part like a human hand near a base station or a user equipment are disclosed. A plurality of radar pulses is transmitted from a communication device in succession and the reflected plurality of radar pulses is received sampled and adaptively processed to remove transmit and receive antenna mutual coupling and clutter from stationary objects near the body part. In one aspect the adaptive processing is accomplished with a single tap adaptive filter. The processed signal may be used to determine if there is a human body part near the communication device allowing the device to determine whether it is safe for the device to transmit a millimeter wave communication signal.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for channel and/or resource selection for sidelink communications. In some cases, a transmitter user equipment UE may transmit, on a sidelink channel used for communicating with other UEs, a control message indicating at least one range, monitor for feedback associated with detection of the control message by one or more other UEs within the indicated range, and transmit data if the feedback indicates at least that the sidelink channel is free.

Abstract: An apparatus is disclosed for concurrent wireless communication and object sensing. In an example aspect, the apparatus includes one or more antennas and a wireless transceiver coupled to the one or more antennas. The wireless transceiver is configured to transmit, via the one or more antennas, a communication and sensing signal during a given uplink time slot. The communication and sensing signal comprises an uplink signal associated with the given uplink time slot and a radar signal. The radar signal temporally overlaps at least a portion of the uplink signal.

Abstract: A wireless device may identify a first subband in an unlicensed radio frequency spectrum band used to communicate control traffic. The wireless device may identify a second subband in the unlicensed radio frequency spectrum band used to communicate data traffic. The first subband and the second subband may be different. The wireless device may reserve the first subband for a first duration of time for a plurality of wireless devices. The reservation may be based at least in part on an enhanced self-clear-to-send (self-CTS) transmitted over the first subband.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support a sensing charging subscription. In a first aspect, a method of wireless communication includes receiving first location information associated with a first mobile entity. The method also includes transmitting an alert based on the first location information and path information configured to model multiple paths associated with an intersection region. The multiple paths include a first path that is curved. The path information defines multiple line segments to model the first path. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may belong to a group of UEs that includes at least a second UE and a third UE. The first UE may perform a channel access procedure and, when the channel access procedure is successful, may transmit a first positioning reference signal (PRS) over a sidelink communication link to the second and third UEs. The first UE may transmit the first PRS during a first time interval of a transmission window. Based on receiving the first PRS, the second UE may perform a channel access procedure and may transmit a second PRS to the first UE during a second time interval of the transmission window. The second PRS may be multiplexed (e.g., using frequency division multiplexing (FDM) or code division multiplexing (CDM)) with at least a third PRS transmitted by the third UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may detect an available bandwidth for transmission of a sidelink positioning reference signal. The transmitter UE may transmit the sidelink positioning reference signal in the available bandwidth, wherein a duration of the sidelink positioning reference signal is based at least in part on the available bandwidth. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may determine parameters for congestion metrics based on a type for a channel access procedure associated with a sidelink transmission. The user equipment may determine a channel access procedure type for a sidelink channel transmission, and determine a limit for a channel occupancy (e.g., a channel occupancy ratio) based on the type. The user equipment may compare the channel occupancy with the limit to determine whether to transmit the sidelink channel transmission, based on whether the channel is available. In some aspects, the user equipment may additionally perform the channel access procedure (e.g., a listen before talk procedure) to determine whether to transmit the sidelink channel transmission. The user equipment may also perform channel measurements to obtain a congestion metric (e.g., a channel busy ratio) based on a threshold before transmitting the sidelink channel transmission.
